The Ford Fiesta B-Spec is intended to be Ford's offering for the newly created B-Spec racing class, which allows racers a (relatively) affordable way to go road racing in production cars.
Based on the same Fiesta available to consumers, the B-Spec cars have their interiors gutted to make way for a rollcage, a bucket seat, race harness and ballast, designed to keep weight levels even among the various cars. Engine work is minimal and rules are still in flux, but certain vehicles will have restrictors fitted to the intake no word yet if the Fiesta will be subject to this handicap.
Tires and suspension will also be subject to the same strict regulations, but again, rules are still being worked out. Ford is evidently behind the program in a big way, and we're looking forward to a full field when racing gets under way in 2012.
